A series of earthquakes devastated the Harappan civilization (it never recovered)

Floods and other natural forces, like rivers changing courses (earthquakes), ended this civilization

Harappa was located in the Indus River valley

 Harappa was discovered in 1921.

By 1900 B.C., simple village life replaced the Harappan civilization

By 1500 B.C., a new group of people, called the Aryans (meaning "noble ones"), began to migrate to the Indus River Valley 

These Aryans were semi-nomadic herders of horses and cattle

The Aryan peoples built simple houses, but were great horse riders and used wheeled chariots

Harappa is famous for the first system of standardized weights

The Aryans were a bunch of tribes

In Persian, Aryan means free and noble

In India, the name Arya was a term used by the Aryan speakers

Aryans belonged to the Indo-European people

People had begun spreading rumors and theories from the Aryans

Eventually, the Aryans became known as the Vedic People

They expanded their territory and adopted agriculture

They grew from villages to kingdoms

The Vedic people believed in polytheism (believing in many gods)

Brahmins (priests) did religious rituals in Sanskrit (ancient Indian language)

Their religion became known as Brahmanism, or early Hinduism

Brahmanism rituals and hymns (religious song or poem to god) were written in books called Vedas (the oldest of the Vedas is the Rig Veda)

A social class system was developed in ancient India

People were born into one of four social categories, but also by professional deeds and good behavior

The social categories were called Varnas

You married within your Varna

Your work was based on your social class, too
